They don't explain what event-driven means, but AFAIK it's based on diffs between frames, which highlight motion and de-emphasise overall brightness/exposure:

  I believe the important point about event cameras is the diffs are per-pixel and entirely asynchronous, so there is no concept of a frame. The video data is simply a stream of events which encode the time and location of a brightness change. For an immediate full-scene change (like removing the lens cap), you’d get a stream that happens to update every pixel, but there’s no particular guarantee about the ordering.

  That's incorrect. Event cameras are different hardware devices than your traditional camera.
